How do I know when a name will be released for re-registration?

In order for a name to be released for registration, it must complete the RGP period (30 days) as well as the RHP period (5 days). In total, a name can be released for re-registration 35 days after it has been deleted by a registrar, provided that there has been no Restore request received by the registry during the RGP period. To calculate the date a deleted name will be available for registration, add 35 days to the "last updated on" date reflected in the WHOIS.
